Spontaneous development of neuronal cells was recorded around 4-34 days in vitro (DIV) with high-density CMOS array, which enables detailed study of the spatio-temporal activity of neuronal culture. We used the CMOS array to characterize the evolution of the inter-spike interval (ISI) distribution from putative single neurons, and estimate the network(More)
Vicarious trial-and-error (VTE) is a behavior observed in rat experiments that seems to suggest self-conflict. This behavior is seen mainly when the rats are uncertain about making a decision. The presence of VTE is regarded as an indicator of a deliberative decision-making process, that is, searching, predicting, and evaluating outcomes. This process is(More)
Spontaneous evolution of neural cells was recorded around 4-34 days in vitro (DIV) with high-density CMOS micro-electrode array, which enables detailed study of the spatio-temporal activity of cultured neurons. We used the CMOS array to characterize 1) the evolution of activation patterns of each putative neurons, 2) the developmental change in cell-cell(More)
Vicarious trial-and-error(VTE) is a type of conflict-like behavior , observed in route selection tasks (Tolman (1939)). Studies of VTE have shown a correlation between the number of VTEs exhibited by a system with its learning efficiency. At the onset of learning a task, the number of VTEs increases, and when the learning reaches its plateau, it decreases.(More)
—Vicarious trial-and-error(VTE) is a type of conflict-like behavior, observed in route selection tasks where rats have been observed evaluating their possibilities before moving toward one route [1]. Studies of VTE have shown a correlation between the number of VTEs exhibited by a system with its learning efficiency. At the onset of learning a task, the(More)
